A user interface display system that is associated with an electronic lock that provides feedback to a user that is engaging the electronic lock. A user interface display system includes a user interface display to depict to the user feedback patterns with each feedback pattern that is displayed to the user providing the feedback to the user. An electrochromic filter transitions a color depicted by the user interface display to correspond to the feedback pattern depicted by the user interface display. Each feedback pattern that is displayed provides a corresponding color that is associated with the feedback that is provided to the user as the user engages the electronic lock. A controller transitions the electrochromic filter to each color to correspond with the feedback pattern that is displayed by the user interface display so that the transitioned color and the feedback pattern that is displayed is in response to the user engaging the electronic lock.

A display device and apparatus, display control method and storage medium are provided. The display device includes first substrate, first dimming layer, a light-emitting layer, second dimming layer and second substrate which are laminated in sequence; the first dimming layer controls the light emitted from the light-emitting layer and incident onto the first dimming layer to present one of the following two states: reflected but not transmitted into the first dimming layer, and transmitted and emergent from one side where the first substrate lies; the second dimming layer controls the light emitted from the light-emitting layer and incident onto the second dimming layer to present one of the following two states: reflected but not transmitted into the second dimming layer; and transmitted and emergent from one side where the second substrate lies. The case that the double-faced images displayed by the display apparatus are mirror images may be avoided.

A light-based output device may be used to display images, symbols, and other information for a user of a system such as a vehicle. A display may be formed from a display layer, a covering layer that covers the display layer, and components such as force and touch sensors and electronic shutters. Haptic feedback may be provided using actuators that are coupled to the covering layer. A movable button member may be used to press the covering layer outwardly within an opening, thereby creating a portion of the covering layer that protrudes from other portions of the covering layer. The button member may also be placed in a position in which the covering layer on the button member is flush with other portions of the covering layer. A touch sensor may be incorporated into the covering layer and may overlap a display and areas outside the display.

Described examples include a process that includes illuminating a spatial light modulator at a first illumination level during a first bit-plane and stopping illumination at a beginning of a second bit-plane subsequent to the first bit-plane. The process also includes resuming illumination after a settling period of the spatial light modulator at a second illumination level for a time period such that a total illumination energy during the second bit-plane is equivalent to an intended illumination energy for the second bit-plane at the first illumination level and stopping illumination at the second illumination level before a subsequent third bit-plane.

The disclosure relates to displays. In one arrangement a plurality of pixels are provided. Each pixel comprises a first optical element reversibly switchable between at least two optical states, and a second optical element reversibly switchable between at least two optical states. The first optical element overlaps spatially with the second optical element in an overlap region when viewed from a viewing side of the display, such that an overall optical effect for the overlap region is defined by a combination of the optical state of the first optical element and the optical state of the second optical element. Row signal lines and column signal lines allow individual addressing of each pixel by applying a combination of a row control signal and a column control signal to the pixel. A driving controller applies the row control signals and the column control signals to the pixels. For each pixel, the same row signal line and column signal line can be used to switch the first optical element and the second optical element independently of each other.

A tintable window is described having a tintable coating, e.g., an electrochromic device coating, for regulating light transmitted through the window. In some embodiments, the window has a transparent display in the window's viewable region. Transparent displays may be substantially transparent when not in use, or when the window is viewed in a direction facing away from the transparent display. Windows may have sensors for receiving user commands and/or for monitoring environmental conditions. Transparent displays can display graphical user interfaces to, e.g., control window functions. Windows, as described herein, offer an alternative display to conventional projectors, TVs, and monitors. Windows may also be configured to receive, transmit, or block wireless communications from passing through the window. A window control system may share computational resources between controllers (e.g., at different windows). In some cases, the computational resources of the window control system are utilized by other building systems and devices.

Example implementations relate to a projector and an electronic ink display. For example, a system may include an electronic ink display device and a projector device. The electronic ink display device may display first content, and the projector device may project second content onto the electronic ink display device such that the second content is overlaid on the first content.
